GASOLENE STORAGE-TANK.

Specification of Letters Patent.

Patented Nov5, 1918.

Application filed. August 29, 1917. Serial No. 188,830.

To all whom t may concern Be it known that I, PAUL GERHARD Koor,

` a subject oi' the King of Great Brita-in, and

a resident of the town of Summerland, in the Province of BritishColumbia, Canada, have invented cert-ain new and useful Improvements inGasolene Storage-Tanks, ot which the followingl is a specification.

My invention relates to improvements in tanks in which gasolene is keptin storage, and the obj ect of my invention is to provide a storage tankthe use of which enables the owner of the same to tell at a glance theamount of gasolene in the tank, the amount taken out, and the amountpart in, and which provides for greater economy in the handling of theoil than when it is purchased in `drums lor barrels, thereby providing adevice which is of great convenience and util-y ity to private carowners, garages, or lfarmers living in places remote from a gasolenesupply station.

I attain this object by the construction illustrated in the accompanyingdrawing in which the gure shows a face view yoii'my device in elevationand partly in section.

l `1 indicates the tank in which the gasolene is storedA which tank isplaced underground,

as shown, and isprovided with a suitable filling pipe .2 fitted with` aremovable strainer A3, also a vent pipe having a lid 5 perforated in itscenterlwith a small hole through which a wire or tine chain 6 maybepassed, to the lower end of which wire or chain is attacheda weightedfloat 7.

Disposed at a suitable height above the;l

tank l is a dial plate 8 divided into ten parts and marked with thenumerals 1 to 9, each division being equal to one gallon, from which itwill'be seen that, in the present instance, ten gallons may beregistered on the dial, although the dial may be made anyv size and mayhave any number of divisions. The arrangement shown, however, indicatesa very handy and compact formo'f the device. Rotatably mounted on thedial is a hand 9 which I call the registering hand, the hub whichcarries the same extending through the dial on an aXle so that there maybe secured thereto and behind the dial a small pulley 10, indicateddotted, around which pulley is passed the wire or chain 6, the wire orchain then dropping downwardly and having secured to its end a weight 11arranged in front of a vertically disposed divided scale 12, eachdivision of which indicates ten gallons, the number of divisions beingsuch that the highest division indicates the capacity of the tank, inthe present case, eighty gallons.

4Rotata'bly mounted- 0n the dial so that it Y may be manually operated,and free of the registering hand, is Y another hand 13, which I call the.marker hand, while in one cornerofthe. dial is provided an opening 14Cbehind -which is rotatably mounted for manual operation a disk 15,indicated by Vthe dotted line,which disk is divided similarly to thescale 12 and may be moved so that the vnumerals with which it is markedwill appear at theopening 14, as indicated in the drawing, the number40being shown, corresponding ,to the position of the weight 11, ashereinafter more fully describech 16 indicates a double-acting pump inconnection with the suction pipe 1 7 and the disf,

charge lpipe 1 8, the `suction pipe being provided with va removablestrainer 19 andthe discharge lpipe with a supply hose 20on the j endyofwhich isV also iitted a removablev strainer 21, while on the upper endotthe discharge pipe is arranged al cap 22 having normally.closedfadjustable .air-holes 23 which may be opened; to VfacilitateYthe emptyingof the hose. f

24: indicates metal case or housing in which the several parts arenclosed, which case is provided with a door in front .but which has notbeen shown in orderto more clearly illustrate the arrangement.

.Having thus indicated the? principal'parts Vof my invention I will nowdescribe brieiiy its operation.

Referring to the drawing it will be noted that the weight 11 is in the40 division of the scale 12 and that the registering hand is at 2. Thisindicates that there are 42 gallons in the tank, because the level ofthe weight indicates the tens of gallons and the numerals on the dialthe number vof gal lons between 1 and 10. Thus if ten gallons were nowtaken out the float level would drop in the tank, raising the weightinto the 30 division of the scale, so that the reading would then be 32gallons, that is, 30 on the scale and 2 on the dial. If ve gallons wereput in, however, the weight would still remain in the 40 division, as itdoes not move out of a division onV the scale until a complete turn ofthe registering hand is effected, but thehand would move to 7 on thedial, showing that lthere were now 47 gallons in the tank. From the'foregoing the purpose of the weight ll and the scale l2 will beunderstood.

rl`he reading, as already `stated and as shown in the drawing, indicatesthat there are l2 gallons in storage. Suppose now that it is desired totake out one gallon. The marker hand is set to l on the dial, whichwould indicate Lll gallons, as the disk l5 is already set as shown, andthe pump is then operated until the registering hand drops to the markerhand, thus showing exactly the amount taken out and recording at thesame time the amount left in storage.

Should it be desired to add more gasolene to the tank the marker hand isfirst set at the same point as the registering hand and then thegasolene is poured in through the Filling pipe 2, causing the floatlevel to rise and moving the registering hand around the dial andlowering the weight 11 on the scale. That is to say, suppose theregistering hand is at 2 on the dial, as shown, and the weight is in theLO division, thus indicating 42 gallons, and some gasolene is to beadded. The marker hand would be moved to 2 on the dial and the gasolenepoured in, raising the level until the registering hand stood at, say, Son the dial. Then the difference between the marker and the registeringhands would show the exact amount added, in this case, 6 gallons.

In leaving the tank the marker hand may be set at the same point as theregistering hand so that on returning after any period during which thedevice may not be in use it will at once be seen whether there has beenany loss by evaporation, leakage, or any other causes, as in that eventthere would be a difference in the position of the two hands.

It will thus be seen that I have invented a gasolene storage tank whichprovides a great convenience for residents in localities remote fromsupply stations, which indicates at a glance the amount of gasolene instorage, the amount taken out, and the amount put in, and in whichlosses due to evaporation, leakage, or other causes may be readilyascertained.

that I claim as my invention is:

l. In a device ot' the class described, in combination, a tank having aHeat, a graduated index dial, a pointer operated by the float andcooperating with the index graduations, a graduated scale readable inconjunction with the index graduations, a weight operated by the floatand cooperating with the scale graduations, said weight and said pointerbeing together adapted to indicate respectively on the said scale andindex dial as the tank level alters the measure of the tank contents.

2. In a device of the class described, in combination, a tank having afloat, a graduated index dial, a pointer operated by the float andcooperating with the index graduations, a graduated scale, a weightoperated by said float and cooperating with the scale graduations, asecond pointer rotatably mounted on said dial also cooperating with thegraduations thereotl and adapted for manual operation and a rotatabledisk graduated similarly to the said scale, the first-mentioned pointerand weight being together adapted to indicate respectively on the saidindex and scale as the tank level alters the measure of the tankcontents and the second-mentioned pointer and said disk being adapted tobe set conjointly so as to provide a record of the amount of alterationin the level of the tank contents.

Dated at Summerland, B. C., this 16th day of August, 1917.
